The high bit of all characters is ignored.
The commands are case insensitive.
Command List
This section lists all commands and queries implemented in this instrument.
Note that there are no dependent parameters, coupled parameters, overlapping commands,
expression program data elements or compound command program headers; each command is
completely executed before the next command is started. All commands are sequential and the
operation complete message is generated immediately after execution in all cases.
The following nomenclature is used:
<rmt>
<RESPONSE MESSAGE TERMINATOR>
<nrf>
A number in any format. e.g. 12, 12·00, 1·2 e1 and 120 e-1 are all accepted as the
number 12. Any number, when received, is converted to the required precision
consistent with the use then rounded to obtain the value of the command.
<nr1>
A number with no fractional part, i.e. an integer.
<nr2>
A number in fixed point format e.g. 11·52, 0·78 etc.
<n>
The number of the output (1 or 2) or associated status register to which the
command relates. On the XEL30-3DP, '1' is the Master (right-hand output) and '2' is
the Slave (left-hand output).
The commands which begin with a
Common commands. All will function when used on the other interfaces but some may be of little
use.
Instrument Specific Commands
For commands specified as 'WITH VERIFY' the operation is completed when the parameter
being adjusted reaches the required value to within ±5% or ±10 counts, whichever is the greater.
If the value fails to settle within these limits within 5 seconds then the Verify Timeout bit (bit 3) is
set in the Standard Event Status Register and the operation is completed at the end of the
timeout period.
The Operation Complete bit (bit 0) in the Standard Event Status Register is only ever set by the
*OPC command. The *OPC (or the *OPC?) command can be used for device synchronization
due to the sequential nature of remote operations.
V<n> <nrf>
Set output <n> to <nrf> Volts
V<n>V <nrf>
Set output <n> to <nrf> Volts with verify
OVP<n> <nrf>
Set output <n> over voltage protection trip point to <nrf> Volts
I<n> <nrf>
Set output <n> current limit to <nrf> Amps
OCP<n> <nrf>
Set output <n> over current protection trip point to <nrf> Amps
V<n>?
Returns the set voltage of output <n>
The response is V <n> <nr2><rmt> where <nr2> is in Volts
I<n>?
Returns the set current limit of output <n>
The response is I <n> <nr2><rmt> where <nr2> is in Amps
OVP<n>?
Returns the voltage trip setting for output <n>
The response is VP<n> <nr2><rmt> where <nr2> is in Volts
OCP<n>?
Returns the current trip setting for output <n>
The response is CP<n> <nr2><rmt> where <nr2> is in Amps
